S…S INTERACTIONS IN CRYSTAL STRUCTURES
(Serbian Crystallographic Society, 2013)
The thiol side chain in cysteine (-CH2SH) has an important structural role in many proteins and often participates in enzymatic reactions, serving as a nucleophile. To find out whether S-S contacts between thiol groups ...
2-Alkylidene-4-oxothiazolidine S-oxides: synthesis and stereochemistry
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
A series of 5-unsubstituted and 5-substituted 2-alkylidene-4-oxothiazolidine-S-oxides were synthesized by the sulfur-oxidation with m-CPBA. The stereochemistry of 5-substituted sulfoxides was determined by means of NMR ...
Long term changes in trophic status and environmental parameters of Grlište reservoir, Serbia / Dugoročne promene u trofičkom statusu i ekološkim parametrima akumulacije Grlište, Srbija
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2013)
In the purpose of monitoring the change of trophic status and water quality in the reservoir Grlište, in the period of 20 years, once a month sampling of water was conducted at two places. The obtained results were used ...
Unusual mode of reactivity of 2-alkylidene-4-oxothiazolidine S-oxides under the Pummerer reaction conditions
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
The reactivity of 2-alkylidene-4-oxothiazolidine S-oxides under the Pummerer reaction conditions, using Ac2O, TFAA, SOCl2 and SOBr2 as initiators, has been examined. Almost all reactions proceeded with absolute regioselectivity ...
Magnetic Anisotropy of the C-C Single Bond
(Wiley-V C H Verlag Gmbh, Weinheim, 2013)
Anisotropic effects are broadly used in NMR spectroscopy for structure elucidation. With the development of computational methods it has become possible to quantify the effects and obtain further insight into their origin. ...
H-1 NMR Chemical Shifts of Cyclopropane and Cyclobutane: A Theoretical Study
(American Chemical Society (ACS), 2013)
This study was undertaken in order to rationalize the peculiar H-1 NMR chemical shifts of cyclopropane (delta 0.22) and cyclobutane (delta 1.98) which are shifted upfield and downfield with respect to larger cycloalkanes ...

(Beograd : Društvo za elektroniku, telekomunikacije, računarstvo, automatiku i nuklearnu tehniku, 2013)
U ovom radu je prikazan način realizacije mikrogredica na Si supstratu {100} orijentacije postupcima zapreminskog mikromašinstva. Rastvor za anizotropno nagrizanje je bio vodeni rastvor 30 tež. % KOH na temperaturi od 80C. ...
A simple two-phase route to polyaniline/gold nanocomposites
(Belgrade : Serbian Chemical Society, 2013)
Combining the electrical, optical, and magnetic properties of polyaniline (PANI) with
excellent chemical and physical properties of gold nanoparticles (Au NPs) is an efficient
way to create novel functional nanomaterials ...
Optical and structural characterization of silver/polystyrene nanocomposites by in-situ bulk radical polymerization
(Belgrade : Serbian Chemical Society, 2013)
Nanocomposites (NCs) with different amount of silver nanoparticles (Ag NPs) embedded
in polystyrene (PS) matrix were prepared by in situ radical polymerization. In order to
achieve homogeneous distribution of Ag NPs in ...
Electrooxidation of p-nitrophenol on organobentonite modified electrodes
(Elsevier, 2013)
A natural bentonite, modified with different quaternary ammonium cations, hexadecyl trimethylammonium, (HDTMA), dodecyl trimethylammonium (DTMA) and tetramethylammonium (TMA), was used as an electrode material in a ...
